Hi, I’m trying to run the opcua-client on a raspberry Pi4 but I get this error:
Traceback (most recent call last): File “/usr/local/bin/opcua-client”, line 5, in from uaclient.mainwindow import main File “/usr/local/lib/python3.9/dist-packages/uaclient/mainwindow.py”, line 15, in from asyncua import ua File “/usr/local/lib/python3.9/dist-packages/asyncua/init.py”, line 13, in from .client import Client File “/usr/local/lib/python3.9/dist-packages/asyncua/client/init.py”, line 1, in from .client import Client File “/usr/local/lib/python3.9/dist-packages/asyncua/client/client.py”, line 5, in from cryptography.hazmat.primitives.asymmetric.types import PrivateKeyTypes ModuleNotFoundError: No module named ‘cryptography.hazmat.primitives.asymmetric.types’
I am using raspios-bullseye-arm64. I tried to upgrade the cryptography library but it broke all the OS. Maybe it is a problem with the operating system version or what could be the problem? thank you very much for your kind help.
